To a whom it may concern:

Be it known that we, GEORGE L. GUYER and ARTHUR .(J. GAMBLE, citizens of the United States, residing at Wcssington, in the county of Hand and State of South Dakota, have invented new and useful Improvements in Incubators; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

- This invention relates to certain new and useful improvements in incubators, and-the most essential object of the invention is to provide an incubator having noveland efficient means attached thereto whereby the heat in the incubator may be prevented from rising or falling below a given temperature and at the same time to provide .a device which is simple in construction and inexpensive to manufacture.

More particularly the invention provides an incubator having the above set forth novel means for preventing the heat from rising or falling below a given temperature and comprising an oscillating rod, one end of which is suitably connected with the waterregulator inside of the incubator and the other end of the rod forming electrical contact with a yoke mounted upon a screwthreaded elongated stud when said oscillatiug rod rocks. The remainder of this device comprises an electric bell, switch, and battery, which are mounted as shown in the accompanying drawings.

This inwention} comprises further objects and combinations of elements which will be hereinafter more fully described, and shown in the accompanyingdrawings, and the novel features thereof will be particularly pointed out by the appended claim.

To obtain a full and correct understanding of the details of construction and combinations of features, elements, and advantages, reference is to be had to the hereinafter set forth description in connection with the accompanying drawings, wherein Figure 1 is a side elevation of the incubator, partlybroken away, showing part of the water regulator and the relative connection with the alarm device; and Fig 2 is an enlarged detail perspective view of the 'alar m device removed or detached from the incubator.

Making renewed reference to the accomto a base 5, as shown clearly in Figs. 1 and 2 of the drawings. Said oscillating rod is adjustably held by a thumb-screw 6, as shown in Fig. 2 of the drawings. The end 7 of said oscillating rod is bent at 8, said bent portion being adapted to havecontact with the arms of a yoke 9 as said oscillating rod isoscillated, as will be readily understood from the drawings in connection with the herein set forthdescription.

Adjacent to the bent portion 8 of the rod is mounted a weight 10, as shown clearly in the drawings. Mounted upon a standard 1 1 is an electric bell 12, having binding-posts 13 and 14, the binding-post 13 having electrical connections 15 with a screw-threaded elongated stud 16, upon which the yoke 9 is adjustably held, said screw-threaded elongated stud being properly secured, as at 17, to the base 5, as shown clearly in the drawings. The binding-post 14 is provided with electrical connection 18, which is connected to a switch 19,

which is also secured to the standard 11. Said switch 19 is provided with an electrical connection 20, which is connected to a battery .21, said battery having electrical connection .22 with the base of the stirrup 4, as shown clearly in the accompanying drawings.

The manner in which the alarm is given when the heat of the incubator rises or falls below a given temperature will be readily understood from an examination of the drawings in connection with the foregoing detailed description.

From the foregoing it will be plainly observed that by the provision of a device above described and shown in the accoma 'panying drawings a very ellicicnt alarm de-,

vice for incubators is provided which is sim-. ple in construction and inexpensive to manufacture.

Having thus fully described the invention, what is claimedas new and useful by the protection of Letters Patent. is-. i

A device of the character described, comprising an incubator having a Water re ulat or a base mounted adjacent to said incu ator, a

. stirrup mounted upon'said base, an oscillating rod journaled in said stirrup, one end of said rod being connected to the water-regu-- lator, a screw-threaded elongated stud mounted upon said base, a yoke adjustably carried by said stud and adapted to have I electrical contacts for'the other end of said oscillating rod, a bell, a switch, and battery having electrical ,;connections withthe stir- 15 ru and said screwthreaded elongated stud.
